The Paul Scherrer Institute (PSI) provides the world's highest intensity DC muon beam of $\mathcal{O}(10^{8})\,\mu^{+}/$s at 28$\,$MeV/c. The muCool collaboration is developing a device which converts such a beam of cm-size and MeV-energy into a low-energy beam of sub-mm size and 1$\,$eV energy spread by achieving a compression of the 6-dimensional phase space by 10 orders of magnitude with a prospected efficiency of $10^{-3}$. In this talk, the working principle of the muCool device and the results from the 2019 beam time are presented. Supported by SNF project 200020_172639.
